RKS1J470MCNAHJGS

The RKS1J470MCNAHJGS is a surface-mount conductive-polymer aluminum solid electrolytic capacitor offering 47 µF nominal capacitance at a 63 V rated voltage. It is built for general-purpose electronic designs that require compact SMD power capacitance with low ESR and robust ripple-current capability.

Designed for demanding thermal and longevity requirements, this capacitor supports an operating temperature range of –55°C to 125°C and a rated load life of 3000 hours at 125°C, providing reliable performance in space-constrained power circuits.

Key Features

• Capacitance & tolerance — 47 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated voltage — 63 V rated voltage suitable for higher-voltage power rails.
• Low dissipation factor — tanδ = 0.12 (measured at 20°C, 120 Hz) for reduced loss in AC conditions.
• Low ESR — 40 mΩ equivalent series resistance measured at 20°C/100 kHz, enabling efficient high-frequency performance.
• High ripple-current capability — 110 mA at 120 Hz (low-frequency) and 1.1 A at 300 kHz (high-frequency) for effective smoothing and decoupling under dynamic loads.
• Leakage current specification — 148 µA leakage current, specified after standard conditioning.
• Long-life, high-temperature endurance — 3000 hours rated life at 125°C to support extended reliability in elevated-temperature environments.
• Compact SMD package — radial can SMD construction, size φ8 × 10 mm, supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Regulatory compliance — RoHS compliant.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and smoothing on higher-voltage rails where 63 V rating and 47 µF capacitance are required.
• High-frequency decoupling — Low ESR (40 mΩ @100 kHz) and 1.1 A ripple capability at 300 kHz help manage fast transient currents in compact SMD designs.
• High-temperature electronics — 3000-hour endurance at 125°C supports sustained operation in elevated ambient or board-level temperatures.

Unique Advantages

• High ripple tolerance: Specified ripple currents of 110 mA (120 Hz) and 1.1 A (300 kHz) enable reliable filtering under variable load conditions.
• Low-loss operation: Low tanδ (0.12) and low ESR (40 mΩ) reduce dissipation and improve efficiency in power-conversion and filtering stages.
• Thermal endurance: Rated for 3000 hours at 125°C, delivering extended service life in thermally demanding applications.
• SMD-ready packaging: Compact φ8 × 10 mm radial can in embossed carrier taping with moisture-proof packing streamlines automated assembly and storage.
• Clear electrical limits: Nominal 47 µF, 63 V rating, and defined leakage current (148 µA) make selection and design margining straightforward.
